OpenJDK and Docker

Dockerfiles and build scripts for generating various Docker Images related to OpenJDK. Currently this builds OpenJDK images with hotspot and Eclipse OpenJ9 on Ubuntu and Alpine Linux.

Supported Architectures

• Hotspot is supported on aarch64, ppc64le, s390x and x86_64.
• Eclipse OpenJ9 is supported on ppc64le, s390x and x86_64.

Build and push the Images with multi-arch support

# Steps 1-3 needs to be run on all supported arches.
# i.e aarch64, ppc64le, s390x and x86_64.

# 1. Clone this github repo
     $ git clone https://github.com/AdoptOpenJDK/openjdk-docker

# 2. Build images and tag them appropriately
     $ cd openjdk-docker
	 # version = 8|9|10
     $ ./build_latest.sh $version

# 3. The above script generates a script (push_commands.sh) that has the right commands to push to
#    hub.docker.com. Make sure to login to hub.docker first
     $ cat ~/my_password.txt | docker login --username foo --password-stdin
     $ ./push_commands.sh

# Steps 4-5 needs to be run only on x86_64

# 4. build_latest.sh and push_commands.sh should be run on all supported architectures to build and
#    push images to the docker registry. The images should now be available on hub.docker.com but
#    without multi-arch support. To add multi-arch support, we need to generate the right manifest
#    lists and push them to hub.docker.com. The script generate_manifest_script.sh can be used to
#    generate the right manifest commands. This needs to be run only on x86_64 after docker images
#    for all architecures have been built and made available on hub.docker.com
     $ ./generate_manifest_script.sh $version

# 5. generate_manifest_script.sh generates a script manifest-commands.sh, that creates the manifest
#    list and pushes them to hub.docker.com. 
     $ ./manifest_commands.sh

# We should now have the proper manifest lists pushed to hub.docker.com to support multi-arch pulls.

Info on other scripts

# Run generate_latest_sums.sh to get the shasums for the latest binaries on adoptopenjdk.net
  $ ./generate_latest_sums.sh $version

# You should now have two files, hotspot_shasums_latest.sh and openj9_shasums_latest.sh. These will
# have the shasums for the latest version for each of the supported arches for hotspot and
# Eclipse OpenJ9 respectively.

# You can now run update_multiarch.sh to generate the Dockerfiles for all supported arches for both
# hotspot and Eclipse OpenJ9.
  $ ./update_multiarch.sh $version

# build_latest.sh will do all of the above and build the docker images for the current arch with the
# right set of tags
